Utilization of the remote monitoring of cardiac implantable electronic devices in a diverse demographic cohort: Insights from a single-center observation.

BACKGROUND: Despite its clinical benefits, patient compliance to remote monitoring (RM) of cardiac implantable electronic devices (CIEDs) varies and remains under-studied in diverse populations. OBJECTIVE: We sought to evaluate RM compliance, clinical outcomes, and identify demographic and socioeconomic factors affecting RM in a diverse urban population in New York. METHODS: This retrospective cohort study included patients enrolled in CIED RM at Montefiore Medical Center between December 2017 and May 2022. RM compliance was defined as the percentage of days compliant to RM transmission divided by the total prescribed days of RM. Patients were censored when they were lost to follow-up or at the time of death. The cohorts were categorized into low (≤30%), intermediate (31-69%), and high (≥70%) RM compliance groups. Statistical analyses were conducted accordingly. RESULTS: Among 853 patients, median RM compliance was 55%. Age inversely affected compliance (p < .001), and high compliance was associated with guideline-directed medical therapy (GDMT) usage and implantable cardioverter defibrillator (ICD)/cardiac resynchronization defibrillator (CRTD) devices. The low-compliance group had a higher mortality rate and fewer regular clinic visits (p < .001) than high-compliance group. Socioeconomic factors did not significantly impact compliance, while Asians showed higher compliance compared with Whites (OR 3.67; 95% CI 1.08-12.43; p = .04). Technical issues were the main reason for non-compliance. CONCLUSION: We observed suboptimal compliance to RM, which occurred most frequently in older patients. Clinic visit compliance, optimal medical therapy, and lower mortality were associated with higher compliance, whereas insufficient understanding of RM usage was the chief barrier to compliance.

Acute Hemodynamic Compromise After Transcatheter Aortic Valve Replacement Due to Dynamic Left Ventricle Obstruction: A Systematic Review.

Acute hemodynamic compromise after transcatheter aortic valve replacement (TAVR) because of dynamic left ventricle (LV) obstruction (LVO), also known as suicide LV, is an infrequent but severe complication of TAVR that is poorly defined in previous studies. Understanding this complication is essential for its prompt diagnosis and optimal treatment. We conducted a systematic literature review using PubMed, Embase, Web of Science, and Medline databases for studies describing acute hemodynamic compromise after TAVR because of dynamic LVO or suicide LV. Each study was reviewed by 2 authors individually for eligibility, and a third author resolved disagreements. From a total of 506 studies, 25 publications were considered for the final analysis. The majority of patients with this condition were women demonstrating a hypertrophic septum, a small ventricle, and hyperdynamic contractility on pre-TAVR echocardiographic assessment. An intraventricular gradient before TAVR was found in half of the cases. Acute hemodynamic compromise after TAVR because of dynamic LVO manifested mainly as significant hypotension and occurred most often immediately after valve deployment. The LV outflow tract was the most common site of obstruction. Advanced therapies were required in nearly 65% of the cases. In conclusion, acute hemodynamic compromise after TAVR because of dynamic LVO occurred almost invariably in women. Echocardiography before TAVR may offer essential information to anticipate this complication. LV outflow tract obstruction appears to carry the highest risk of developing this phenomenon. Advanced therapies should be promptly considered as a bailout strategy in patients with hemodynamic collapse refractory to medical therapy.

Epidemiologic and Clinical Characteristics of Marantic Endocarditis: A Systematic Review and Meta-analysis of 416 Reports.

Nonbacterial thrombotic endocarditis (NBTE) is a distinctive condition marked by the presence of aseptic fibrin depositions on cardiac valves due to hypercoagulability and endocardial damage. There is a scarcity of large cohort studies clarifying factors associated with morbidity and mortality of this condition. A systematic literature review was performed utilizing the PubMed, Embase, Cochrane, and Web-of-Science databases to retrieve case reports and series documenting cases of NBTE from inception until September-2022. A descriptive analysis of basic characteristics was carried out, followed by multivariate regression analysis to identify risk factors associated with morbidity and mortality. A total of 416 case reports and series were identified, of which 450 patients were extracted. The female-to-male ratio was around 2:1 with an overall sample median age of 48 (interquartile range [IQR]:34-61). Stroke-like symptoms were the most common presentation and embolic phenomena occurred in 70% of cases, the majority of which were due to stroke. Cancer was associated with higher embolic complications (aOR:6.38, 95% CI = 3.75-10.83, p < 0.01) in comparison to other NBTE etiologies, while age, sex, and vegetation size were not (p > 0.05). All-cause in-hospital mortality was 36%, with cancer etiology being associated with higher mortality: 56% (aOR:3.64, 95% CI = 1.57-8.43, p < 0.01) in comparison to other NBTE etiologies:19%. A significant decrease in NBTE mortality was seen in recent years in comparison to admissions that occurred during the 20th century (aOR:0.07, 95% CI = 0.04-0.15, p < 0.01). While there has been an observed improvement in overall in-hospital mortality rates for patients admitted with NBTE in recent years, it is important to note that cases associated with a cancer etiology are still linked to high morbidity and mortality during hospitalization.

Hypertension Management in Peripheral Artery Disease: A Mini Review.

Lower extremity peripheral artery disease (PAD) affects over 230 million adults globally, with hypertension being one of the major risk factors for the development of PAD. Despite the high prevalence, patients with hypertension who have concomitant PAD are less likely to receive adequate therapy. Through this review, we present the current evidence underlying hypertension management in PAD, guideline-directed therapies, and areas pending further investigation. Multiple studies have shown that both high and relatively lower blood pressure levels are associated with worse health outcomes, including increased morbidity and mortality. Hence, guideline-directed recommendation involves cautious management of hypertensive patients with PAD while ensuring hypotension does not occur. Although any antihypertensive medication can be used to treat these patients, the 2017 American Heart Association/American College of Cardiology (AHA/ACC), 2017 European Society of Cardiology (ESC), and 2022 Canadian guidelines favor the use of angiotensin-converting enzyme inhibitors (ACEI) or angiotensin receptor blockers (ARB) as the initial choice. Importantly, data on blood pressure targets and treatment of hypertension in PAD are limited and largely stem from sub-group studies and post-hoc analysis. Large randomized trials in patients with PAD are required in the future to delineate hypertension management in this complex patient population.

Confounding clinical picture in the diagnosis of left ventricular and valvular masses: a case report.

Background: Masses in the heart and valves have a broad differential diagnosis including infective and rheumatic causes as well as primary or metastatic tumours. Diagnosis involves delineating the location, shape, and origin of the mass/masses and considering the clinical context. This case outlines the work-up and approach to diagnosing a cardiac mass along with imaging findings of a unique secondary metastatic mass in the left ventricle (LV). Case summary: A 69-year-old female with past medical history of metastatic lung cancer treated with radiotherapy and breast cancer treated with mastectomy presented with dyspnoea and fever. Due to concern for infective endocarditis, transthoracic echocardiogram (TTE) was performed revealing 2 cm × 0.72 cm finger-like, echo-lucent, mobile mass, appearing to originate from LV lateral wall, protruding into the LV cavity, along with valvular masses on mitral and tricuspid valves. Initial differential diagnosis included benign pathologies, but due to the clinical suspicion of malignancy, cardiac MRI was performed which revealed a broad-based mass with invasion into the LV lateral wall and delayed gadolinium enhancement, suggestive of metastatic tumour. The patient was given Aspirin to prevent embolization and eventually underwent hospice care. Discussion: Atypical appearing cardiac masses can be seen on TTE. Cardiac magnetic resonance imaging (MRI) should be used for definite diagnosis in cases where clinical features do not match the echocardiographic findings.

Differences between Lower Extremity Arterial Occlusion vs. Stenosis and Predictors of Successful Endovascular Interventions.

Background and Objectives: In patients with peripheral artery disease, there is insufficient understanding of characteristics that predict successful revascularization of the lower extremity (LE) chronic total occlusions (CTOs) and baseline differences in demographic, clinical, and angiographic characteristics in patients with LE CTO vs. non-CTO. We aim to explore these differences and predictors of successful revascularization among CTO patients. Materials and Methods: Two vascular centers enrolled LE-CTO patients who underwent endovascular revascularization. Data on demographics, clinical, angiographic, and interventional characteristics were collected. LE non-CTO arterial stenosis patients were compared. A total of 256 patients with LE revascularization procedures were studied; among them, 120 had CTOs and 136 had LE stenosis but no CTOs. Results: Aspirin use (Odds ratio, OR: 3.43; CI 1.32-8.88; p = 0.011) was a positive predictor whereas a history of malignancy (OR: 0.27; CI 0.09-0.80; p = 0.018) was a negative predictor of successful crossing in the CTO group. The CTO group had a higher history of myocardial infarction (29.2 vs. 18.3%, p = 0.05), end-stage renal disease (19.2 vs. 9.6%, p = 0.03), and chronic limb-threatening ischemia as the reason for revascularization (64.2 vs. 22.8%, p < 0.001). They were more likely to have advanced TransAtlantic Inter-Society Consensus (TASC) stages, multi-vessel revascularization procedures, longer lesions, and urgent treatment. Conclusions: The use of aspirin is a positive predictor whereas a history of malignancy is a negative predictor for successful crossing in CTO lesions. Additionally, LE-CTO patients have a higher incidence of comorbidities, which is expected given their higher disease burden. Successful endovascular re-vascularization can be associated with baseline clinical variables.

Incidence and Prognostic Implications of Cardiac-Implantable Device-Associated Tricuspid Regurgitation: A Meta-Analysis and Meta-Regression Analysis.

New-onset or worsening tricuspid regurgitation (TR) is a well-established complication encountered after cardiac implantable electronic devices (CIEDs). However, there are limited and conflicting data on the true incidence and prognostic implications of this complication. This study aimed to bridge this current gap in the literature. Electronic databases MEDLINE, Embase, and Web of Science were systematically searched from inception to March 2023, for studies reporting the incidence and/or prognosis of CIED-associated new or worsening TR. Potentially eligible studies were screened and selected according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. A random effect model meta-analysis and meta-regression analysis were performed, and I-squared statistic was used to assess heterogeneity. A total of 52 eligible studies, with 130,759 patients were included in the final quantitative analysis with a mean follow-up period of 25.5 months. The mean age across included studies was 69.35 years, and women constituted 46.6% of the study population. The mean left ventricular ejection fraction was 50.15%. The incidence of CIED-associated TR was 24% (95% confidence interval [CI] 20% to 28%, p <0.001) with an odds ratio of 2.44 (95% CI 1.58 to 3.77, p <0.001). CIED-associated TR was independently associated with an increased risk of all-cause mortality (adjusted hazard ratio [aHR] 1.52, 95% CI 1.36 to 1.69, p <0.001), heart failure (HF) hospitalizations (aHR 1.82, 95% CI 1.19 to 2.78, p = 0.006), and the composite of mortality and HF hospitalizations (aHR 1.96, 95% CI 1.33 to 2.87, p = 0.001) in the follow-up period. In conclusion, CIED-associated TR occurred in nearly one-fourth of patients after device implantation and was associated with an increased risk of all-cause mortality and HF hospitalizations.

Comparison of in-hospital outcomes and complications of leadless pacemaker and traditional transvenous pacemaker implantation.

AIMS: Since their introduction in 1958, traditional cardiac pacemakers have undergone considerable upgrades over the years, but they continue to have a complication rate of ∼3.8%-12.4%. There are no randomized controlled trials comparing outcomes of leadless pacemakers (LPM) with single-chamber transvenous pacemakers (TV-VVI). The aim is to assess the differences in the procedural complications and in-hospital outcomes between LPM and TV-VVI implants. METHODS AND RESULTS: We queried the national inpatient database from 2016 to 2019 to include adult patients undergoing LPM and TV-VVI. Admissions for leadless and single-lead transvenous pacemakers were identified by their appropriate ICD-10 codes. Complications were identified using ICD-10 codes that mostly represent initial encounter. The difference in outcomes was assessed using multivariable logistic regression and 1:1 propensity score matching between the two cohorts. Thirty-five thousand four hundred thirty expanded samples of admissions were retrieved of which 27 650 (78%) underwent TV-VVI with a mean age 81.3 ± 9.4 years and 7780 (22%) underwent LPM with a mean age of 77.1 ± 12.1 years. The LPM group had a higher likelihood of in-hospital mortality [adjusted odds ratio (aOR): 1.63, 95% CI (1.29-2.05), P < 0.001], vascular complications [aOR: 7.54, 95% CI (3.21-17.68), P < 0.001], venous thromboembolism [aOR: 3.67, 95% CI (2.68-5.02), P < 0.001], cardiac complications [aOR: 1.79, 95% CI (1.59-2.03), P < 0.001], device thrombus formation [aOR: 5.03, 95% CI (2.55-9.92), P < 0.001], and need for a blood transfusion [aOR: 1.54, 95% CI (1.14-2.07), P < 0.005]. The TV-VVI group had higher likelihood of in-hospital pulmonary complications [aOR:0.68, 95% CI (0.54-0.87), P < 0.002] and had a need for device revisions [aOR:0.42, 95% CI (0.23-0.76), P < 0.004]. CONCLUSION: There is a higher likelihood of all-cause in-hospital mortality and complications following LPM implantation in comparison to TV-VVI. This could be related to higher co-morbidities in the LPM group. Clinical trials aimed to accurately compare these two groups should be undertaken.

Assessment of the Utilization of Validated Diagnostic Predictive Tools and D-Dimer in the Evaluation of Pulmonary Embolism: A Single-Center Retrospective Cohort Study from a Public Hospital in New York City.

INTRODUCTION: A significant increase in the use of computed tomography with pulmonary angiography (CTPA) for the diagnosis of pulmonary embolism (PE) has been observed in the past twenty years. We aimed to investigate whether the validated diagnostic predictive tools and D-dimers were adequately utilized in a large public hospital in New York City. METHODS: We conducted a retrospective review of patients who underwent CTPA for the specific indication of ruling out PE over a period of one year. Two independent reviewers, blinded to each other and to the CTPA and D-dimer results, estimated the clinical probability (CP) of PE using Well's score, the YEARS algorithm, and the revised Geneva score. Patients were classified based on the presence or absence of PE in the CTPA. RESULTS: A total of 917 patients were included in the analysis (median age: 57 years, female: 59%). The clinical probability of PE was considered low by both independent reviewers in 563 (61.4%), 487 (55%), and 184 (20.1%) patients based on Well's score, the YEARS algorithm, and the revised Geneva score, respectively. D-dimer testing was conducted in less than half of the patients who were deemed to have low CP for PE by both independent reviewers. Using a D-dimer cut-off of <500 ng/mL or the age-adjusted cut-off in patients with a low CP of PE would have missed only a small number of mainly subsegmental PE. All three tools, when combined with D-dimer < 500 ng/mL or 95%. CONCLUSION: All three validated diagnostic predictive tools were found to have significant diagnostic value in ruling out PE when combined with a D-dimer cut-off of <500 ng/mL or the age-adjusted cut-off. Excessive use of CTPA was likely secondary to suboptimal use of diagnostic predictive tools.

A rare case of concurrent mitral and aortic valve aneurysms in the setting of infective endocarditis.

Key Clinical Message: Mitral valve aneurysm is a rare imaging finding most caused by infective endocarditis. The concurrent presence of an aortic valve aneurysm is unique and foretells a severe presentation that would require valve replacement during the same admission. Abstract: A 42-year-old male patient presented with intermittent fever, night sweats, and weight loss for 2 months. TEE showed a rare finding of concurrent mitral and aortic valve aneurysms, and blood cultures grew streptococcus mutans. His infective endocarditis was successfully treated with antibiotics and placement of mechanical mitral and aortic valves.

Right-to-Left Shunt in Divers with Neurological Decompression Sickness: A Systematic Review and Meta-Analysis.

OBJECTIVE: The aim of this study was to assess the association between the presence of a right-to-left shunt (RLS) and neurological decompression sickness (NDCS) and asymptomatic brain lesions among otherwise healthy divers. BACKGROUND: Next to drowning, NDCS is the most severe phenotype of diving-related disease and may cause permanent damage to the brain and spinal cord. Several observational reports have described the presence of an RLS as a significant risk factor for neurological complications in divers, ranging from asymptomatic brain lesions to NDCS. METHODS: We systematically reviewed the MEDLINE, Embase, and CENTRAL databases from inception until November 2021. A random-effects model was used to compute odds ratios. RESULTS: Nine observational studies consisting of 1830 divers (neurological DCS: 954; healthy divers: 876) were included. RLS was significantly more prevalent in divers with NDCS compared to those without (62.6% vs. 27.3%; odds ratio (OR): 3.83; 95% CI: 2.79-5.27). Regarding RLS size, high-grade RLS was more prevalent in the NDCS group than the no NDCS group (57.8% versus 18.4%; OR: 4.98; 95% CI: 2.86-8.67). Further subgroup analysis revealed a stronger association with the inner ear (OR: 12.13; 95% CI: 8.10-18.17) compared to cerebral (OR: 4.96; 95% CI: 2.43-10.12) and spinal cord (OR: 2.47; 95% CI: 2.74-7.42) DCS. RLS was more prevalent in divers with asymptomatic ischemic brain lesions than those without any lesions (46.0% vs. 38.0%); however, this was not statistically significant (OR: 1.53; 95% CI: 0.80-2.91). CONCLUSIONS: RLS, particularly high-grade RLS, is associated with greater risk of NDCS. No statistically significant association between RLS and asymptomatic brain lesions was found.

Incidence, predictors and outcomes of new onset systolic heart failure following orthotopic liver transplant: A systematic review.

BACKGROUND: New onset Systolic heart failure (SHF), characterized by new onset left ventricular (LV) systolic dysfunction with a reduction in ejection fraction (EF) of <40%, is a common cause of morbidity and mortality among Orthotopic liver transplant (OLT) recipients. Therefore, we aimed to evaluate the prevalence, the pre-transplant predictors, and the prognostic impact of SHF post-OLT. METHODS: We conducted a systematic review of the literature using electronic databases MEDLINE, Web of Science, and Embase for studies reporting acute systolic heart failure post-liver transplant from inception to August 2021. RESULT: Of 2604 studies, 13 met the inclusion criteria and were included in the final systematic review. The incidence of new-onset SHF post OLT ranged from 1.2% to 14%. Race, sex, or body mass index did not significantly impact the post-OLT SHF incidence. Alcoholic liver cirrhosis, pre-transplant systolic or diastolic dysfunction, troponin, brain natriuretic peptide (BNP), blood urea nitrogen (BUN) elevation, and hyponatremia were noted to be significantly associated with the development of SHF post-OLT. The significance of MELD score in the development of post-OLT SHF is controversial. Pre-transplant beta-blocker and post-transplant tacrolimus use were associated with a lower risk of developing SHF. The average 1-year mortality rate in patients with SHF post-OLT ranged from 0.00% to 35.2%. CONCLUSION: Despite low incidence, SHF post-OLT can lead to higher mortality. Further studies are required to fully understand the underlying mechanism and risk factors.

Ethnic and sex-based differences in outcomes after out-of-hospital cardiac arrest: a glimpse of the largest municipal healthcare system in the United States.

Background: Ethnic and sex-based disparity in outcomes after out-of-hospital cardiac arrest (OHCA) may exist and could be due to social factors and inequality in care. We aimed to study whether ethnic and sex-based differences in out-of-hospital cardiac arrest outcomes occurred in a safety net hospital within the largest municipal healthcare system in the United States. Methods: We conducted a retrospective cohort study of patients successfully resuscitated from an OHCA and brought to New York City Health + Hospitals/Jacobi, from January 2019 to September 2021. Out-of-hospital cardiac arrest characteristics, do not resuscitate and withdrawal of life-sustaining therapy orders, and disposition data were collected and analyzed using regression models. Results: Out of 648 patients screened, 154 were included (48.1% women). On multivariable analysis, sex [odds ratio (OR): 0.84; 95% CI: 0.30-2.4; P=0.74] and ethnic background (OR: 0.80; 95% CI: 0.58-1.12; P=0.196) did not predict discharge survival. No significant sex difference in do not resuscitate (P=0.76) or withdrawal of life-sustaining therapy (P=0.39) orders was found. Younger age (OR: 0.96; P=0.04) and initial shockable rhythm (OR: 7.26; P=0.01) independently predicted survival, both at discharge and at one year. Conclusions: Among patients resuscitated after an out-of-hospital cardiac arrest, neither sex nor ethnic background predicted discharge survival and no sex differences in end-of-life preferences were found. These findings are distinct from those of previously published reports. Given the unique population studied, distinct from those of registry-based studies, socioeconomic factors likely served as bigger drivers of out-of-hospital cardiac arrest outcomes rather than ethnic background or sex.

A Meta-Analysis on the Impact of High BMI in Patients Undergoing Transcatheter Aortic Valve Replacement.

BACKGROUND: A paradoxical association of obesity with lower risk of transcatheter aortic valve replacement (TAVR) outcomes has been reported. We aimed to systematically review the literature and compare TAVR-related morbidity and mortality among individuals with overweight or obesity and their peers with normal body mass index (BMI). METHODS: PubMed and Embase databases were systematically searched for studies reporting TAVR outcomes in different BMI groups. Separate meta-analyses were conducted for studies reporting hazard ratios (HR) and odds ratios/relative risks. Short- and mid-/long-term outcomes were examined. RESULTS: 26 studies with a total of 74,163 patients were included in our study. Overweight was associated with lower risk of short-term mortality (HR: 0.77; 95% CI: 0.60-0.98) and mid-/long-term mortality (HR: 0.79; 95% CI: 0.70-0.89). Obesity was associated with lower risk for mid-/long-term mortality (HR: 0.79; 95% CI: 0.73-0.86), but no difference was observed in short-term mortality, although a trend was noted (HR: 0.87l 95% CI: 0.74-1.01). Individuals with obesity demonstrated an association with higher odds of major vascular complications (OR: 1.33; 95% CI: 1.05-1.68). Both overweight (OR: 1.16; 95% CI: 1.03-1.30) and obesity (OR: 1.26; 95% CI: 1.06-1.50) were associated with higher likelihood for receiving permanent pacemakers after TAVR. CONCLUSION: Individuals with overweight and obesity were associated with lower mortality risk compared to those with normal BMI but with higher likelihood of major vascular complications and permanent pacemaker implantation after TAVR.

Pulmonary Embolism in Women: A Systematic Review of the Current Literature.

Cardiovascular disease is the leading cause of death in women. Pulmonary embolism (PE) is the third most-common cause of cardiovascular death, after myocardial infarction (MI) and stroke. We aimed to evaluate the attributes and outcomes of PE specifically in women and explore sex-based differences. We conducted a systematic review of the literature using electronic databases PubMed and Embase up to 1 April 2022 to identify studies investigating PE in women. Of the studies found, 93 studies met the eligibility criteria and were included. The risk of PE in older women (especially >40 years of age) superseded that of age-matched men, although the overall age- and sex-adjusted incidence of PE was found to be lower in women. Risk factors for PE in women included age, rheumatologic disorders, hormone replacement therapy or oral contraceptive pills, pregnancy and postpartum period, recent surgery, immobilization, trauma, increased body mass index, obesity, and heart failure. Regarding pregnancy, a relatively higher incidence of PE has been observed in the immediate postpartum period compared to the antenatal period. Women with PE tended to be older, presented more often with dyspnea, and were found to have higher NT-proBNP levels compared to men. No sex-based differences in in-hospital mortality and 30-day all-cause mortality were found. However, PE-related mortality was higher in women, particularly in hemodynamically stable patients. These differences form the basis of future research and outlets for reducing the incidence, morbidity, and mortality of PE in women.

Remdesivir in the Treatment of COVID-19: A Propensity Score-Matched Analysis from a Public Hospital in New York City Assessing Renal and Hepatic Safety.

While the relative efficacy of remdesivir as a therapeutic agent in selected patients with COVID-19 has been established, safety concerns have been raised regarding potential nephrotoxicity and hepatotoxicity. Our main objective was to investigate the kidney- and liver-related safety outcomes in patients with COVID-19 treated with remdesivir in a public hospital in New York. A propensity score-matched retrospective study was conducted in hospitalized patients with COVID-19 from 1 June 2020 to 10 March 2021. A total of 927 patients were included in this study (remdesivir: 427, non-remdesivir: 500; women: 51.8%; median age 61 years; median BMI: 28.5 kg/m2). Matching without replacement yielded a cohort of 248 patients (124 in each group). In the matched cohort, the remdesivir group had a significantly lower rate of acute kidney injury (AKI) (12.1% vs. 21.8%, p = 0.042), a lower rate of acute liver injury (ALI) on the verge of statistical significance (7.3% vs. 14.5%, p = 0.067), and non-significantly lower death rate (13.7% vs. 16.1%, p = 0.593) compared to the non-remdesivir group. Multivariable analyses revealed that patients treated with remdesivir were found to be associated with a significantly lower likelihood for AKI (OR: 0.40; 95% CI: 0.24−0.67, p < 0.001), no association was found for ALI (OR: 0.68; 95% CI: 0.35−1.30, p = 0.241), while a trend towards an association of patients treated with remdesivir with a lower likelihood for in-hospital death was observed (OR: 0.57; 95% CI: 0.32−1.01, p = 0.053). In conclusion, no safety concerns with regards to renal and liver outcomes were raised in patients with COVID-19 treated with remdesivir. Instead, there were signals of possible nephroprotection and improved in-hospital mortality.

Post-COVID-19 Pulmonary Fibrosis.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has infected millions worldwide with a high mortality rate due to a lack of definitive treatment. Despite having a wide range of clinical features, acute respiratory distress syndrome (ARDS) has emerged as the primary cause of mortality in these patients. Risk factors and comorbidities like advanced age with limited lung function, pre-existing diabetes, hypertension, cardiovascular diseases, and obesity have increased the risk for severe COVID-19 infection. Rise in inflammatory markers like transforming growth factor ß (TGF-ß), interleukin-6 (IL-6), and expression of matrix metalloproteinase 1 and 7 (MMP-1, MMP-7), along with collagen deposition at the site of lung injury, results in extensive lung scarring and fibrosis. Anti-fibrotic drugs, such as Pirfenidone and Nintedanib, have emerged as potential treatment options for post-COVID-19 pulmonary fibrosis. A lung transplant might be the only life-saving treatment. Despite the current advances in the management of COVID-19, there is still a considerable knowledge gap in the management of long-term sequelae in such patients, especially concerning pulmonary fibrosis. Follow up on the current clinical trials and research to test the efficacy of various anti-inflammatory drugs is needed to prevent long-term sequelae early mortality in these patients.

Current Advancement in Diagnosing Atrial Fibrillation by Utilizing Wearable Devices and Artificial Intelligence: A Review Study.

Atrial fibrillation (AF) is a common arrhythmia affecting 8-10% of the population older than 80 years old. The importance of early diagnosis of atrial fibrillation has been broadly recognized since arrhythmias significantly increase the risk of stroke, heart failure and tachycardia-induced cardiomyopathy with reduced cardiac function. However, the prevalence of atrial fibrillation is often underestimated due to the high frequency of clinically silent atrial fibrillation as well as paroxysmal atrial fibrillation, both of which are hard to catch by routine physical examination or 12-lead electrocardiogram (ECG). The development of wearable devices has provided a reliable way for healthcare providers to uncover undiagnosed atrial fibrillation in the population, especially those most at risk. Furthermore, with the advancement of artificial intelligence and machine learning, the technology is now able to utilize the database in assisting detection of arrhythmias from the data collected by the devices. In this review study, we compare the different wearable devices available on the market and review the current advancement in artificial intelligence in diagnosing atrial fibrillation. We believe that with the aid of the progressive development of technologies, the diagnosis of atrial fibrillation shall be made more effectively and accurately in the near future.

Prevalence of menopausal symptoms among women in Vadodara, Central Gujarat: The urban-rural divide.

Aim: The aim of this article is to estimate prevalence of menopausal symptoms among women in the menopausal age group and study the urban-rural differences. Methods and Design: Analytical cross-sectional study conducted in rural and urban field practice areas of a tertiary care center affiliated to Medical College, where 290 women (145 each from urban and rural areas) were interviewed to measure prevalence of menopausal symptoms. Forty-one symptoms were divided into 'Psycho-somatic' (17 symptoms), 'genito-urinary (9 symptoms)' and musculo-skeletal (5 symptoms) domains. The prevalence of each of these symptoms is reported as proportion and the differences in the median scores in the two groups were tested using Mann-Whitney U test. Results: From among 145 women each, in urban and rural settings, most common psychosomatic symptoms were physical exhaustion-fatigue (73.1%), difficulty climbing stairs (59.3%), sleep problems (45.2%), body ache (43.4%), and hot flushes (41.4%). Among the urban participants, most common was physical exhaustion (42.1%), difficulty climbing stairs (62.1%), anger (46.9%), sleep problems (45.5%), and irritability (42.1%), while among the rural participants they were physical exhaustion (66.2%), difficulty climbing stairs (56.6%), insomnia (54.5%), and body ache (46.2%).
